Oh, yeah, yeah. I have aging turned on, so the heirs and their spouses will get old and die. Kids who don't get heired will, of course, age if I put them in their own houses and play with them, but logically speaking most of them will be immortal.

A lot of my inspiration is coming from rikkulidea's legacies, and she does the same thing. So she'll be in, say, gen eight, and one of the spares from gen two will walk by on the sidewalk, flaunting their immortality.
